Ebrahimi Araghizad, Arash and Özlü, Emre and Budak, Erhan (2017) Geometrical optimization of broaching tools by leveling the cutting forces. In: 8th International Symposium on Machining, Antalya, Turkey
This study presents an approach to broaching tool design optimization for a user-defined final complex-shape by considering the cutting forces. Although broaching process is the only machining operation in order to machine complicated profiles without using a rotary motion, it is one of the least studied one in the literature. A broach tool has a complex multi cutting teeth which are placed in a row by the rise per tooth corresponding to the uncut chip thickness. Developing a method to generate an optimized broach tool design based on constant cutting forces can eliminate potential problems (reducing tool life, chipping, bad surface quality and etc.) while decreasing its length. In this study, a method is developed in order to minimize the length of the broach, increase tool life and quality of the final part leading to reduction of whole process cost.
